ULTRASONIC DIAGNOSTIC APPARATUS |
摘要 |
An ultrasonic diagnosing apparatus having an ultrasonic observation system for observing an ultrasonic tomographic image of a portion of a body of patient and an optical observation system for observing an optical image of the portion, a direction indicator is superimposed on an ultrasonic tomographic image displayed on a monitor screen, and the direction indicator is rotated on the monitor screen in accordance with the rotation of the ultrasonic tomographic image. The ultrasonic diagnosing apparatus further has a system for compensating for a deviation between the ultrasonic tomographic image displayed on the monitor screen and the optical image due to a twist of a flexible shaft which is extended in an insertion section of the apparatus to rotate an ultrasonic vibrating element arranged in a distal end of the insertion section.
